POST-MOLD.

Specification of Letters Patent.

Patented Feb. 17,1914.

Application filed January 22, 1912. Serial No. 672,584.

To all whom it may concern:

Be it known that I, WILLIAM W. BEEBE, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented a new and useful Post-Mold, of which the following is a specification.

The device forming the subject-matter of this application, is adapted to be employed for the fashioning of a concrete fence post.

The invention aims to provide a troughshaped mold including a removable pallet, means being provided for rotating the mold, so as to dispose the open side uppermost, and so as to throw the weight of the molded post upon the pallet, whereupon the pallet and the post may readily be removed.

A further object of the invention is to provide novel means for holding the removable pallet assembled with the remaining portions of the trough.

lVith the foregoing and other objects in view, which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the. details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of invention herein disclosed can be made within the scope of what is claimed without departing from the spirit of the lnvention.

In the accompanying draW1ngs,-F1gure 1 shows the invention in front elevation;

Fig. 2 is a top plan; Fig. 3 is an end elevation; Fig. 4: is a transverse section; Fig. 5 is an enlarged transverse section of the molding trough; and Fig. 6 is a perspective of the post which is fashioned in the machine herein disclosed.

In carrying out the invention there is provided as a primary element, a supporting frame 1, which may be of any desired form. The end portions of the frame 1 terminate in rearwardly extended supports 11, having functions which will be pointed out hereinafter. Across the front of the frame 1, adjacent its upper end, extends a top bar 2, and

. across the frame, adjacent its lower end, ex-

tends the bottom bar 3. The bars 2 and 3 are connected by an upright brace 4;, having a shoulder 5 in one edge thereof. The end portions of the frame 1 are connected, at the rear of the frame, by intersecting braces 6.

Mounted for rotation upon the supporting frame 1 is a trough, in which the post is molded. This trough includes a shaft 7, journaled for rotation in the frame 1, and extended longitudinally of the frame. Secured in its intermediate portion to the shaft 7, and extended transversely of the frame 1, intermediate the ends thereof, is a lever 8, the handle end 9 of which is resilient, so that this end of the lever normally presses against one edge of the brace 4t, and automatically engaged beneath the shoulder 5. The rear end 10 of the lever 8 is connected by a retractile spring 12 with some suitable portion of the frame 1, such, for instance, as the intersecting braces 6. The trough further includes a series of rear arms 14:, which are secured to the shaft 7. The back plate 15 is secured to the rear arms 14, and constitutes one wall of the trough. In the back plate 15 there are openings 16, through which may protrude the wire-holding elements which are molded into the post. J ournaled for rotation upon the shaft 7 are a series of forward arms 17, certain of these arms being located beyond the ends of the frame 1, and others of these arms being located intermediate the ends of the frame. The upper, forward ends of the arms 17 are connected by a brace 18, and the rear ends of the arms 17 extend beyond the shaft 7, and are counterweighted, as shown at 19, so as to swing the forward ends of the arms normally upwardly.

The end walls 21, preferably of triangular form, are united by means of bolts 22 or like connecting elements, with the back plate 15. These end walls 21 diverge, so as to facilitate the removal of the finished post from the trough. Duplicate openings 23 are provided in the back plate 15, which openings are adapted to receive the securing bolts 22, so that the end walls 21 may be moved longitudinally of the trough, in order to fashion a shorter post. A removable pallet is provided, the same being adapted to be slipped beneath the end walls 21. Latches 2 1 are pivoted, as shown at 25, to the back plate 15, these latches 24 having in their lower edges, notches 26 or like elements, adapted to engage the outer edge of the pallet 20, to hold the pallet against the end walls 21. The forward arms 17 serve to maintain the inner edge of the pallet 20 engaged beneath the back plate 15.

In practical operation, the parts are positioned as shown in Figs. 2 and 3, the spring 12 acting upon the lever 8, to rotate the shaft 7 and to tilt the trough so that the back plate 15 thereof will come into engagement with the supports 11, whereupon the open side of the trough is disposed uppermost. The latches 24 are engaged with the inner edges of the pallet 20, and the counterweighted, forward arms 19 will also serve to press the pallet 20 against the end walls 21 and to hold the inner edge of the pallet 20 engaged beneath the back plate 15. Concrete is inserted into the trough, and tamped down, the concrete being struck off along the upper edges of the back plate 15 and of the collar 20. In this manner, a triangular post will be formed. After the concrete has set sufficiently, the handle end 9 of the lever is swung downwardly, putting the spring 12 under tension, the handled end of the lever engaging beneath the shoulder 5 in the brace at. The trough will thus be swung forwardly, into approximately the position shown in Fig. 4, the pallet 20 being disposed in an approximately horizontal position. Owing to the fact that the end walls 21 diverge, the pallet 20 and the molded post may readily be slid forwardly, and the post be removed from the trough. The handled end 9 of the lever 8 is then disengaged from be neath the shoulder 5 in the brace 4, Whereupon the spring 12 will swing the back plate into approximately the position shown in Fig. 3. Another pallet 20 may then be placed upon the pivotally mounted arms 17, the arms 17 and the pallet being swung upwardly, until the pallet comes into engagement with the end walls 21, whereupon the latches 2 1 may be engaged over the up per edges of the pallet.

From the foregoing it will be seen that the operation of fashioning a triangular fence post may be carried on with great rapidity, one pallet being readily replaced by another, so that there may be no delay in the molding operation, while the concrete is taking a final set.

Having thus described the invention, Whatis claimed is 1. In a post mold, a supporting frame; a shaft journaled in the frame; a back plate fixed with respect to the shaft; end walls secured to the back plate; a movable pallet abutting against the end walls; means for holding the pallet against the end walls; and means for rotating the shaft.

2. In a post mold, a supporting frame; a shaft journaled in the frame; a back plate fixed with respect to the shaft; diverging end walls secured to the back plate; a removable pallet abutting against the end walls; means for holding the pallet against the end walls; and means for rotating the shaft.

3. In a post mold, a supporting frame, a shaft journaled in the frame; a back plate fixed with respect to the shaft; end walls secured to the back plate; a removable pallet abutting against the end walls; a counterweighted arm fulcrumed upon the shaft and serving as a support for the pallet; the arm engaging the inner edge of the pallet to hold the inner edge of the pallet against displacement; and means for holding the outer edge of the pallet against displacement.

4. In a post mold, a supporting frame; a shaft ournaled in the frame, rear arms secured to the shaft, a back plate secured to the rear arms and spaced from the shaft and a pallet engaged between the back plate and the shaft; a front arm fulcrumed interme diate its ends upon the shaft and counterweighted to engage the inner edge of the pallet; and a latch connecting the outer edge of the pallet with the back plate.

5. In a post mold, a supporting frame; a trough including a shaft journaled in the frame; rear arms secured to the shaft, a back plate secured to the rear arms, the rear arms constituting a support for the back plate, end walls secured to the back plate and a removable pallet engaged beneath the end walls and the back plate; means fulcrumed on the shaft for holding the pallet at its in ner edge engaged with the back plate adjacent the shaft; and a movable latch engaging the back plate and the pallet to hold the outer edge of the pallet engaged with the end walls.

In testimony that I claim the foregoing as my own, I have hereto affixed my signa ture in the presence of two witnesses.
